The outspoken comedienne was so upset the discount chain wouldn't stock her book, she handcuffed herself to a shopping trolley to protest.

"My book has been banned by Costco and it's on the national New York Times bestseller list six weeks in a row," Rivers shouted into her megaphone at Costco in Burbank.

"They have no right; the First Amendment says I can sell my book."

“People should have the right to have the literature they want,” she told KTLA News. “This is the beginning of Nazi Germany.”

“This is a store that sells 300 rolls of toilet paper at the same time,” she added to KABC. “And I say any customer that buys 300 rolls of toilet paper deserves a funny book to sit on the toilet and read.”

The discount chain allegedly banned her book, I Hate Everything…Starting With Me, because of two inappropriate parody quotes from Marie Antoinette and Wilt Chamberlain on the back cover of the book.

Police were called to put an end to the protest and the 79-year-old left willingly.

The Los Angeles times called the commotion "the best book publicity stunt of 2012 by far".
